Intel® Power Gadget is a software-based power usage monitoring tool enabled for Intel® Core™ processors (from 2nd Generation up to 7th Generation Intel® Core™ processors). Intel® Atom™ processors are not supported. It is supported on Windows* and Mac OS X* and includes an application, driver, and libraries to monitor and estimate real-time processor package power information in watts using the energy counters in the processor. With this release, we are providing functionality to evaluate power information on various platforms including notebooks, desktops and servers. Windows 7* and 32-bit versions of the Intel® Power Gadget for Windows* has ceased development from 3.0.7. Starting with version 3.5 and going forward, only the 64-bit version and Windows 8* will be supported.

Background

Traditional methods to estimate power/energy usage of the processor has always been a cumbersome task that included special purpose tools or instrumentation on the platform along with third party equipment. The motivation for the tool was to assist end-users, ISV’s, OEM’s, developers, and others interested in a more precise estimation of power from a software level without any H/W instrumentation.

New Features

In version 3.0 there are additional features that include estimation of power on multi-socket systems as well as externally callable APIs to extract power information within sections of code. The multi-socket support essentially evaluates the Energy MSR on a per-socket basis and provides an estimate of power draw per socket. The API layer is a set of libraries and dlls that can be called and offers the flexibility to build the tool within code sections of an application. Latest release also includes support for Windows 10*.

Brief Description (Windows version)

Intel® Power Gadget 3.5 consists of the following components. Set of driver and libraries which access and post process the processor energy counter to calculate the power usage in Watts, temperate in Celsius and frequency in GHz (default install directory will be ~\Program Files\Intel\Power Gadget 3.5). A command line version of the tool (PowerLog3.0.exe) is also included

Let you log the power and frequency measurements and save it in a csv format.

Steps

API

Intel® Power Gadget also provides a C/C++ Application Programming Interface (API) for accessing this power and frequency data in your program; the API is supported on Windows and Mac OS X. For more information on the API's, see:

Double click on the desktop shortcut and the GUI will launch

Drag to move the GUI.

Right click the GUI and a pop-up menu will show up allowing you to choose options or close the application. Options have the following parameters. Click “Start Log” button in the GUI to start logging. Press the same button “Stop Log” to stop logging. While it’s logging, red label “REC” will blink in the power chart area.

You can choose to add time-stamp to the log file name or not.

You can choose the log file name.

You can choose to resize the GUI from 100% to 300% by dragging the slider and testing the new size with the “Apply Size” button and accept the changes by pressing “Ok”.

Screen Update Resolution lets you change how often the GUI is updated at runtime. This may range from 50 ms to 1000 ms. (Default set to 1000 ms)

GT Energy (Energy of the processor graphics) – If applicable , some processors for desktops and servers don’t have it or may have use discrete graphics

Only works on 2nd Generation Intel® Core™ processor family or newer. Atom processors not yet supported.

Use only 32-bit installer for 32-bit OS and 64-bit installer for 64-bit OS

Application may hang after running for a long period of time (just close and restart application)
